Finally posting pictures of a project in-process. I have two, this truck in 1:14 scale and a Komatsu D65EX-15 dozer in 1:10 scale. The truck is going faster because I don't have to build an entire undercarriage. This truck is unique cause it is 4-wheel drive, rigid frame, 50-ton, with dual tires all around. I've finished rear axle area and am working on the cab. Front axle is next.

The 1:1 Truck -actually a Payhauler Corp 350C, but close enough.

Front frame is dropped and narrowed. Aluminum "soldered" the modified channel to shape.

Rear cross-member
